Abstract: A  ratchet/release  mechanism  for  a  retrievable  well apparatus and a retrievable well apparatus includes a split ratchet ring engaging threads on a mandrel. Split ring wedge members engage an inclined end of the ratchet ring to maintain the ratchet ring in engagement with the mandrel.  The wedge members are prevented from radial outward movement by a sleeve. A resilient elastomer ring is positioned between the ratchet ring and an  internal  shoulder on the  sleeve.   The  ring compresses to enable the inclined end of the ratchet ring to slide up the wedge members upon movement of the mandrel in a first direction.  The release of the ratchet ring is effected by moving the sleeve. When the wedge members are no longer confined by the sleeve they move radially away from the ratchet ring allowing the ratchet ring to disengage from the mandrel.

Title: Path-based restoration for mesh networks
Inventor: CHAUDHURI SID
IPC: H04L12/56
Filed: 1999-05-03
Granted: 2002-12-24
Abstract: Restoration of service in a mesh network upon the failure of a working channel on a link connecting a pair of nodes is accomplished by first attempting to route traffic on an restoration channel in the same link when such a channel  is available. If such "localized" restoration can not be accomplished, then the  end- point (traffic originating and/or terminating) nodes that are connected by a  path that includes the link having the failed working channel then implements a pre- computed path. Each pre-computed path identifies a collection of channels in  a series of links that connect the end-point nodes (and any intermediate nodes ) so as to bypass traffic around the link having the failed working channel. The pre - computed path information is typically pre-stored in the end-point nodes to enable the end-point nodes to effect rapid restoration in the event localized restoration is not achievable.

Inventor: LEMBCKE JEFFREY J
IPC: E21B47/18
Filed: 1999-09-17
Granted: 2004-11-30
Abstract: The invention relates to valves usable downhole and controlled from the surface hydraulically via control lines or by other techniques. The valve has a minimum flow passage which is preferably oriented along its longitudinal axis and a lateral flow passage which opens upon movement of a valve member via applied control pressure from the surface. Alternatively, the valve comprises a tapered needle movable in a throat. When the valve member shifts, additional flow area is exposed to control the backpressure of a fluid by way of hydraulic pressure control from the surface via the control line. The hydraulic control can be with a single control line acting on a piston attached to the valve member with a return spring opposing such movement, or alternatively, can be carried out with a pair of control lines to actuate reverse movements of the valve member. A pressurized gas chamber can be used to act as the closing force opposing applied pressure from the control line for a return of the valve to its minimum flow or maximum throttle position.  Alternatively, an acoustic, electric or other type of surface-directed signal can change the valve position.

Abstract: The invention relates to a connector system between a first substrate (1) which may be, for example, a back-panel with a male multipoint connector (2), and a second substrate (3) on which a corresponding female multipoint connector (4) is mounted. For centering and coding, the first substrate has a perpendicularly projecting guide pin (6) arranged thereon on which a coding key (7) is mounted which, during connection of first substrate (1) and second substrate (3), is introduced during the mating operation into a coding box (8) having a corresponding counter-coding key (11). The guide pin (6) is clampingly retained in coding box (8) via a spring (10). With centering pins according to IEC 1076-4-102, center-ing of the guide pin (6) in coding box (8) takes place by the cooperation of coding key (7) and counter-coding key (11). For avoiding damage to the spring (10) in coding box (8) in case of longer guide pins, the invention provides for the insertion of an additional centering piece (12) in the coding box (8) between the counter--coding key (11) and the spring (10).
